"The increasing complexity of scientific inquiry has led to a proliferation of multiauthored technical articles. Reports of clinical trials involving patients from several hospitals are usually coauthored by physicians from each participating hospital. Likewise, physics papers reporting results from experiments using subsystems developed at various laboratories generally have authors from each laboratory."

If all of the statements above are true, which one of the following must be true?

the answer is B) Most reports of clinical trials involving patients from several hospitals have multiple authors

As you can see, the answer is literally the second sentence of the stimulus verbatim except that "usually" is replaced by "most". Are the two terms identical in meaning for the purposes of the LSAT? Thanks!

usually as a word means 'more often than not' which would translate into 'more than 50% of the time this certain event will occur.' I believe the LRB has short snippet on usually, but it basically boils down to it meaning most.
